There is the need to make clarifications on the rumours of JAMB grade markups, result swapping and so on. I have listened with amusement to some Jambitos making uneducated assertions and was aghast to hear how they unbundled their (and also parents') hard earned money to pay for modification to the outcomes of JAMB CBT's. Many can attest that such efforts have ended in regret and angry recriminations and accusations.

The fact is that any manipulation is not readily possible at the CBT centre. Unless the proposed JAMB CBT system has been modified, the original proposal has several security features. The not so technical features involves:

1. The setting of five or more different sets of questions for each subject.

2. Each question has a unique ID so that it can be identified.

2. The CBT test server has the ability to serve combinations of such questions so that the possibility of two candidates in the same centre having the same set of questions for the same subject is slim. I.e Maths questions on system A are different in both form, type and numbering from that on system B - similar to paper type on the written tests.

3. Also the possibility of two candidates having the same set of questions for the same subject combination is low. I.e Maths,Eng and Geo questions on system A are, 50% or more, different in both form, type and numbering from that on system B.

4. The CBT server records each candidates response in its database together with the question ID.

5. Finally, the results processing involves the transmittance of the database to JAMB for processing which then issues the results.


Thus it is obvious that manipulation is almost impossible either from the JAMB or CBT centre end. Many might argue that gaming the system is possible if:

1. The CBT centre has the skill or resources to prise all CBT questions out of the CBT server database and give favored candidates all of the CBT questions before hand which will run into pages of paper.

2. The CBT centre has the skill or resources to log into the CBT server database and manipulate the response of a candidate to the test questions.

3. Or if a JAMB staff in the IT section, or higher, with administrative access to the results database is suborned.

Be advised that JAMB has taken all such scenario into consideration and the other technical features and guards (not discussed here) have been implemented to discourage such sabotage. So be informed and do not fall for scam proposals to change results in any way.

DISCLAIMER: I do not work for JAMB or its affiliates but do have requisite experience in the design and implementation of such systems.

Apologies for the inability to take questions.
